ABSTRACT:
A method and apparatus for creating an orthodontic archform and forming an archwire. The method includes positioning the model teeth in a curved archform and making a graphical representation of the archform. An archwire is superimposed over the graphical representation and archwire-segment forming templates, each having an archwire channel of a predetermined shape, are clamped onto segments of the archwire between the brackets to shape each segment so that the archwire as a whole assumes the desired shape of the archform. The archwire is then formed in that shape by heat treatment or by leaving a streamlined form of the templates on the archwire.
